BGO Crystal

Bismuth germanate( Bi4Ge3O12 )commonly abbreviated as BGO, is the crystalline form of an inorganic oxide with cubic eulytine structure, colorless, transparent and insoluble in water. When exposed to the irradiation of high energy particles or other sources, such as gamma-rays, X-rays, it emits a green fluorescent light with a peak wavelength of 480nm. With its high stopping power, high scintillation efficiency, good energy resolution and non-hygroscopic, BGO is a good scintillation material and has been found a wide range of applications in high energy physics,  physics, space physics,  medicine, geological exploration and other industries. Armed with the expertise of crystal growth accumulated in the past year, SICCAS has developed an unique technology for BGO growing and scaled up into quantity production in the R&D Center of the institute. In 1980’s , SICCAS was designated to supply BGO to European Organization in it’s L3 experiment. Now SICCAS has become a world-wide famous BGO producer to meet the customer demands in crystal quality, quantity, cost effectiveness and delivery schedule. The boules up to 4’’ dia.x6” long or equivalent rectangular shape can be cultivated and crystal devices with different shapes can be provided as required.
